With the helpful information in this forum I made a bino from a Zeiss microscope head. I am more than pleased.
I wish to also use a microscope bino on a lighter, smaller (60mm) scope, but the Zeiss head is quite heavy, enough so that it really isn't workable especially with the longer tube of the intended 60mm.
Is there a microscope head that is a lighter option than the Zeiss? The used market is especially appealing for price reasons. (Yes, I have searched, but have only so far come up with weight comparisons of prefab bino units).
I used "wide" 23mm (size) Zeiss eyepieces which worked well and I hope to use the same size in the next bino.
